Summary
A number of nutritional factors affecting α-amylase production by the edible fungus Calvatia gigantea, cultivated in a wheat bran liquid medium, were investigated. The concentration and particle size of wheat bran and the relative concentration of three nitrogen and three mineral sources markedly affected enzyme production. A high amylase yield of 60.4 U ml-1 was obtained when the fungus was cultivated for 5 days at 29°C in a medium containing optimum concentrations of the tested factors. The results provide additional supporting evidence for the versatility of Calvatia gigantea to upgrade a number of low-cost agricultural products to high value biotechnological products.
